My grandfather worked in a factory where they plated metal. Not sure what kind exactly, it was forty five years ago. He would take pennies and other small items and plate them shiny silver colored and gift them to my grandmother and sometimes the kids or grandkids. Obviously a much smaller scale than your stuff but the point is this. Those things were cherished by all for the personal touch and thoughtfulness. That's one heck of a nice gift for the FedEx guy and wife. I know I'm late to this thread but nicely done.
